Notes:

This stalked puffball is called Calostoma or pretty mouth because of the raised orange stoma, which is quite attractive.
The spore-containing peridium is three-layered and protected by a harder cap which falls off at maturity.The inner sac is then exposed and when under pressure, releases its spores through its opening.
Order : Boletales
Family: Calostomataceae
